使用Selenium Webdriver的鼠标悬停不适用于Firefox浏览器

Question

Below are the firefox, gecko driver and selenium versions that I have used for automation scripts: Firefox browser: 52.0 Selenium: 3.0.1 Gecko driver: 0.11.1

Below is my code for mouse hover action:

Actions action = new Actions(driver.getWebDriver());
WebElement mainMenu = driver.findElement(By.xpath("(//*[@class='ciebar__menu-item ciebar__menu-item--has-dropdown medium-4 '])[1]/a"));
WebElement submenuxpath = driver.findElement(By.xpath("(//*[@class='ciebar__menu-item ciebar__menu-item--has-dropdown medium-4 '])[1]/ul/li[1]/a"));
action.moveToElement(mainMenu).moveToElement(submenuxpath).click().build().perform();

This code had worked properly for chrome and IE browser and facing issue only in Firefox. I have tried by upgrading Selenium and Gecko driver, but the that time the browser did not invoke. Below is the error message that is being displayed

Please help.

Looks like the /{session id}/moveto endpoint isn't supported by geckodriver. There is a discussion about this here and a bug report was already filed against Selenium here .
